FS Series NAS configuration
61 Dell PS Series Configuration Guide
Note: With the exception of the IPMI connection paths, corresponding ports on each controller node must
connect to the same SAN switch. This connection pattern is shown in Figure 22.
Connection Paths for FS7500 iSCSI SAN, IPMI and Controller Interconnect
The inter-switch connection sizing guidelines provided in section 8.2.2 also apply to FS7500 SAN design. The
FS7500 mirrors the write cache between controller nodes. To accomplish this, all write operations are
transmitted across the controller interconnect. Thus, it is very important to follow the connection pattern
shown in Figure 22 to ensure corresponding ports are connected to the same switch. This connection pattern
prevents controller interconnect traffic from crossing the inter-switch connection.
